About this study

Official title: A Phase IIB Randomized, Double-Blind, Placebo-Controlled, Multi-Dose Study to Evaluate the Effects of PHENOGENE-1A (Cromolyn) as an Adjuvant Treatment in Subjects With Mild to Moderate Amyotrophic Lateral Sclerosis (ALS)

The purpose of this study is to test the effects of PHENOGENE-1A, which is the treatment under investigation in this study. This research will investigate if PHENOGENE-1A can help people with ALS by measuring their function using the ALS Functional Rating Scale Revised (ALSFRS-R), measuring lung function using pulmonary function tests (PFTs), such as forced vital capacity (FVC), and measuring neuro-inflammatory biomarkers in the blood.

Read the detailed description

This is a Phase IIB, randomized, double-blind, placebo-controlled study designed to assess the effects of PHENOGENE-1A (oral inhalation via dry powder inhaler [DPI]) in subjects with mild to moderate ALS disease. Eligible subjects will be randomized to receive either low dose PHENOGENE-1A (34.2 mg per day: in 2 doses of 17.1 mg and matching placebo BID), high dose PHENOGENE-1A (68.4 mg per day: 34.2 mg BID), or placebo (2 matching placebo capsules BID) (see table below), in a 2:2:1 ratio. Subjects will receive treatment for a duration of 24 weeks. All subjects must be on a stable dose of Riluzole 50 mg BID (100 mg daily) for at least 4 weeks prior to randomization and must continue their Riluzole regimen, 50 mg BID (100 mg daily), as standard-of-care treatment, throughout the 24 week treatment period.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cromolyn Sodium (34.2 mg BID), Cromolyn Sodium (17.1 mg BID) and Riluzole (100 mg) in people with Amyotrophic Lateral Sclerosis (ALS), run by PhenoNet, Inc. at 22 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in Spain, United States, Poland, Czechia, Germany and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact David R Elmaleh, PhD (+1 (617) 784-0490, delmaleh@phenonet.us), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Absolute change in ALSFRS-R total score from baseline to Week 24 (time frame: Baseline to Week 24). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2026.
